Key Features

• Capacitance and Voltage — 10,000 µF (10 mF) nominal capacitance with a 350 V rated voltage and ±20% tolerance, providing substantial DC energy storage for high-voltage circuits.
• Screw Terminal Mounting — Radial can with screw terminals simplifies secure electrical and mechanical connections in panel- or chassis-mounted power assemblies.
• High Ripple Current Capability — Rated ripple currents of 25.9 A at 120 Hz and 36.26 A at 100 kHz support effective smoothing and filtering under high AC ripple conditions.
• Endurance and Temperature Range — 5,000 hours load life at 85°C; operating temperature range from −25°C to +85°C for stable performance across typical industrial environments.
• Leakage and Loss Characteristics — Specified leakage current of 5,000 µA and tangent of loss angle (tan δ) of 0.2, enabling predictable loss and leakage behavior during design validation.
• Electrical Safety and Stability — Insulation resistance greater than 100 MΩ at DC 500 V between terminal and bracket, and AC 2,500 V dielectric withstand for one minute without abnormality, per datasheet specifications.
• Physical Size and Packaging — Form factor φ90 × 140 L (L: 14 × D: 9 cm), supplied in cardboard packing for protection during handling and storage.
• RoHS Compliant — Conforms to relevant RoHS directives as indicated in the product documentation.

Typical Applications

• Power Supply Filtering — Bulk DC filtering and smoothing in high-voltage power supplies where 350 V and high capacitance are required to stabilize the DC bus.
• DC Link / Energy Storage — Energy buffering and DC-link support in converters and inverters that demand high ripple-current capability and long endurance at elevated temperatures.
• Industrial Power Electronics — General-purpose high-voltage applications in industrial systems that need reliable bulk capacitance and robust terminal connections.

Unique Advantages

• Substantial Bulk Capacitance: 10,000 µF at 350 V provides strong energy-storage capacity for smoothing and transient support in high-voltage circuits.
• Designed for High Ripple Loads: Explicit ripple-current ratings at both low and high frequencies (25.9 A at 120 Hz; 36.26 A at 100 kHz) enable designers to size capacitors for real ripple conditions.
• Long Endurance Under Load: 5,000-hour rated life at 85°C under specified ripple conditions supports predictable lifetime planning for industrial equipment.
• Robust Mechanical Termination: Screw terminals ensure secure electrical and mechanical connections for chassis- or bracket-mounted installations.
• Clear Electrical Reliability Specs: Insulation resistance >100 MΩ and AC 2,500 V dielectric proof provide measurable safety margins for terminal-to-bracket isolation.
• Regulatory Compliance: RoHS compliance is documented for deployments requiring restricted-substance conformance.
